UNITED STATES PATENT GFFICE.

DAVID H. BAKER, OF JERSEY CITY, NEW JERSEY.

IMPROVED MODE OF LOCKING RAILROAD-CAR SETS.

Specification forming part of Letters Patent No. 43,753, dated` August 9, 1864.

To all whom it may concern/.-

Be it known that I, DAVID H. BAKER, of Jersey City, in the county of Hudson and State of New J ersey, have invented, made, and applied to use a certain new and useful Improvement in Means for Locking Railroad-Gar Seats; and I do hereby declare the following to be a full, clear, and eXact description of my said invention, reference being had to the annexed drawings, making part of this specification, wherein- Figure l is an elevation of the arms of two seats next thel outside of the car, with the backs locked in place. Fig. 2 is a. similar view with the backs unlocked and free to be turned over, and Fig. 3 is a section of a mod ilication of my locking device. ,y

Similar marks of reference denote the same parts.

Car-seats have heretofore been locked in position (so that the backs could not be turned 'at one operation all the seats included within the length of such bar, whereby the backs can be unlocked simultaneously, and so remain until turned over, or until the passengers are seated, and then said backs can be locked in the position they may stand (regardless of which Way they may be turned) by one move ment of such bar.

In the drawings, a c represent the arms of the car-seats that are aflixed to the sides of the car. b b are the backs of the seats; c c, the back irons or links by which such backs are connected to the center studs, d d, and on which the backs move or swing when being turned over or changed. These parts may be of any usual or desired construction. c c rep resent the usual stops receiving the irons c c. fis a bar fitted in the arms a a., or in the side of the car. ln cases where the arms are not provided at the outer ends of the seats, and at t' z', are -shaped notches in said bar, receiving pins projecting from the iron c c, or the pins may be on the bar f and the -shaped notches in the iron c c, as seen at g g.

By reference to Fig. 2 it will be seen that these pins and notches are so located that the backs of the seats can be freely turned over or changed 5 but if the bar f receives an end- Wise motion the respective pins entering the horizontal parts of the -shaped notches will hold the backs in position and prevent their being changed.

Any suitable means may be employed for giving an end motion to the bar f and for locking the same. I have shown a lever, h, for moving, and. a box-lock, 7c, the bolt of which enters a notch in the bar f, for lookin g said bar stationary in either position.

Fig. 3 shtws a modification in the mode of locking, in which the bar f is provided with hooked arms o near each of the arms a, so that by giving a partial rotation to such shaft or bar f the hooks Will be turned away from or over each of the irons c c, and prevent the back being turned over or changed.

What I claim, and desire to secure by Letters Patent, is

A movable locking-bar, extending along the car the distance of several seats and fitted with pins, hooks, Vor slots, substantially as specified, in combination with the movable backs of the seats and the locking device, whereby said 'backs can be all locked or unlocked simultaneouslyby moving the said bar, 'as set forth.

In witness whereof I have hereunto set my signature this 2d day of October, A. D. 1863.

DAVID H. BAKER.
